Developer's Description

When was the last time you had your eyes tested? You cant remember? Yeah, well, neither do I! With this eye test you can test your vision at home easily and totally free! After doing the tests you should be able decide whether or not you should see an eye doctor. Doing the vision tests is fun, and you can also share the results with your friends on Facebook!**The app is in English! Please don't give me bad ratings because the app is not in your language!**The application has 6 type of eye tests:* Visual acuity tests (based on a Snellen chart, numbers and text, with black or white background)* An Ishihara Color Blindness test* 4 Amsler grid tests* An AMD test for macular degeneration* A Glaucoma survey* A written test aka. how much do you know about the eye?Would you like other vision tests in the app? Tell us! (see our address below)Due to variations in each screen accuracy (screen size, brightness/contrast, resolution) the eye tests are not perfect.Do not consider the tests in the app official tests. These tests only mean to give you an idea whether or not you should see an eye doctor or go on an eye therapy.**Customer satisfaction is important to us. If you have any problems with the app, any development ideas, new or funny eye tests, or questions, please contact us at b2creatived@gmail.com. We will answer as soon as possible, usually within 24 hours.**In order to be able to keep the application free, we need to implement ads. Please do not give us bad ratings because you don't like ads. Rate our application by it's performace, design, compatibilty or anything you want.Some information about the eye:Eyes are organs that detect light and convert it into electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain.Visual acuityVisual acuity, or resolving power, is "the ability to distinguish fine detail" and is the property of cone cells. It is often measured in cycles per degree (CPD), which measures an angular resolution, or how much an eye can differentiate one object from another in terms of visual angles.Perception of colorsColor vision is the faculty of the organism to distinguish lights of different spectral qualities. All organisms are restricted to a small range of electromagnetic spectrum; this varies from creature to creature, but is mainly between wavelengths of 400 and 700 nm. This is a rather small section of the electromagnetic spectrum, probably reflecting the submarine evolution of the organ: water blocks out all but two small windows of the EM spectrum, and there has been no evolutionary pressure among land animals to broaden this range.Rods and conesThe retina contains two major types of light-sensitive photoreceptor cells used for vision: the rods and the cones.Rods cannot distinguish colours, but are responsible for low-light (scotopic) monochrome (black-and-white) vision; they work well in dim light as they contain a pigment, rhodopsin (visual purple), which is sensitive at low light intensity, but saturates at higher (photopic) intensities.Cones are responsible for colour vision. They require brighter light to function than rods require. In humans, there are three types of cones, maximally sensitive to long-wavelength, medium-wavelength, and short-wavelength light (often referred to as red, green, and blue, respectively, though the sensitivity peaks are not actually at these colors).Recent changes:Soon: randomized visual acuity test1.4 Design change.
